In liquid methanol, CH₃OH Which intermolecular forces are present? A) Dispersion, hydrogen bonding and dipole-dipole forces are present. B) Only dipole-dipole and hydrogen bonding forces are present. C) Only dispersion and ion-dipole forces are present. D) Only hydrogen bonding forces are present.

Question

Quizplus · Accepted Answer

Methanol (CH3OH) molecules exhibit dispersion forces due to temporary dipoles, dipole-dipole forces because of the permanent dipole moment (difference in electronegativity between oxygen and hydrogen), and hydrogen bonding due to the presence of a hydrogen atom bonded to an electronegative oxygen atom.
